Do coliphages replace E. coli monitoring?
No. They add viral-indicator context; bacterial indicators remain important in their own methods and regulations.
AquaVerify
Coliphages and viral indicator resources
Guides, research summaries and checklists for somatic coliphages, viral indicators, water treatment evidence and monitoring design.
Direct answer
Use this collection to understand when coliphages add a viral-indicator layer beyond bacterial indicators and how to document the workflow.
- Compare bacterial indicators with somatic or F-specific coliphages.
- Connect matrix, host strain, controls, incubation and PFU reporting.
- Keep source context separate from AquaVerify product orientation.
How to use this collection
Guides, research summaries and checklists for somatic coliphages, viral indicators, water treatment evidence and monitoring design.
- Define the monitoring question first.
- Select the coliphage route and evidence needs.
- Use checklists to prepare sampling, method and report fields.

FAQ
Can AquaVerify help choose a coliphage workflow?
Yes. AquaVerify can map objective, matrix, method, products and traceability needs before a recommendation.
